Do MGS crustal field direction corresponds to those one observed by Mars 3 ? YES ! Comparison of Mars 3 magnetic field with those one of MGS provides evidence that Mars 3 really detected the magnetic field of Martian crust in the early Verigin & Slavin, EPSC 2006-A This observations was not properly interpreted before MGS crustal magnetization discovery.

There is an essential dipole component exists in the multipole moment of planet Mars Further methodology development is necessary for its accurate determination, including consideration of current systems produced by solar wind – Mars interaction Nothern hemisphere: TO THE PLANET Southern hemisphere: FROM THE PLANET Mars Global Surveyor Mars Global Surveyor : Connerney et al., 2001

Estimated peak n e max of the night- side ionization layer corresponds to that one observed by radio occultations of Mars 4,5 and Viking 1,2 spacecraft. Why was the peak of nightside ionization observed in 100% of th s/c radio occultations at but in only 40% of radio occultations at Mars? The reason may be connected with the partial screening of the Martian nightside atmosphere by a weak intrinsic magnetic field of the planet which is completely absent in the case of Venus Verigin et al., JGR, 96(A11), 1991 Haider et al., JGR, 97, 10637, 1992 Martian nightside ionosphere source Martian nightside ionosphere source
